Acoustic research
Understand the sources of sound and the measurements needed to assess quieter flight.
Compare the sources of sound.
These synthetic frequency shapes illustrate a research question. They are not measured spectra or sound-level predictions.
Solid-state EHD
Primary source / Ion-driven airflow
Concept illustration · E0 · not to scale
EHD avoids blade-passage noise. Discharge, power electronics and airflow still require acoustic characterization. VIMANA-X has no measured full-vehicle acoustic result.
